ZTSXLLIM Test Tube Rack, Lab Test Tube Holder, Centrifuge Tube Rack 28 Well

These work great for drying my lad vials exc...!

Has many sizes great product.

So I use 10ml syringes to measure out nutrients for my garden and use more nutrients then the botanical gardens! So these are hard to keep organized and I made my own holder but it was ugly. These here allow me to finally be organized and they look great too. I only need to cut apart 2 of the larger holes so I can put my PH meter and my EC meter and these will be perfect.

Needed plant tubes then realized I also need something to hold them. Not expensive and easy to assemble and use. Will accommodate two size tubes.

I bought this to hold my ScentBird vials. Works perfectly. Smaller holes hold the vials and the larger holes hold the shipping tube and spritzers

As described

Hold test tubes well

These racks are just what I need to properly dry test tubes, 15 ml and 30 ml bottles, and their glass droppers.

Probably polystyrene, stiff plastic. Can not be pressure cooked for sterilization. I would doubt it will handle solvents.

Es de buen material. Los he metido al baño sonico con los tubos de centrífuga y resiste bien.
